Product Description

The qualified decolored oil Cooking Oil Production Line enters into the spiral plate heat exchanger to recover most of the heat, and LD Edible Cooking Oil Refinery Plant sunflower oil processing machine corn oil making machine next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260°C) and then enters the deodorization tower. Shandong Leader Machinery Co.,ltd. The upper layer of combined deodorization tower is the packing structure which Cooking Oil Production Line is mainly used to remove the odor producing components such as free fatty acid (FFA); Shandong Leader Machinery Co.,ltd. the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero. Cooking Oil Production Line Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85°C through the cooler.

Edible oil refining includes a series processing procedures as degumming, neutralization, bleaching, deodorization and winterisation. In general there are two methods of vegetable/edible oil processing, one is physical refining and the other is chemical refining. However, no matter what kinds of reining methods, they are all done with the help of various oil processing equipment and machinery, and are used to refine almost all kinds of oil extracted from oil seeds like sunflower seeds, peanuts , sesame seeds, and soya bean seeds etc.

Main Steps of Edible Oil Refining 1. Crude Oil Degumming: In this step gums in crude oil are removed by hydration with the help of phosphoric acid.2. Neutralization: In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.4. Deodorization: Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.5. Dewaxing (necessary for cold areas)Some kinds of oil like sunflower, maize germ or corn oil have waxes inside, if these impurities are not removed, the oil will freeze easily under low temperature, thus effecting oil quality and appearance. so this process is necessary in extremely cold areas.

Physical RefiningIn Physical Refining, Vegetable Oil is subject to distillation to remove free fatty acids. The alkali treatment is completely avoided. This reduces the amount of waste water and eliminates production of soap. This process is becoming more popular.

Chemical Refining In Chemical Refining, Vegetable Oil is treated with caustic lye for separation of free fatty acids from oil. This is a conventional process that can be applied to all oils. A byproduct of alkali refining is soap-stock, which is used for manufacture of low quality washing soap. Alternately, the soap-stock can be treated with acid to recover fatty acids. The waste-water from refinery requires extensive treatment. This can be avoided by alternate Physical Refining process.Physical RefiningIn Physical Refining, Vegetable Oil is subject to distillation to remove free fatty acids. The alkali treatment is completely avoided. This reduces the amount of waste water and eliminates production of soap. This process is becoming more popular.DegummingThe purpose of Degumming Vegetable Oils is to remove Gums. All oils have hydratable and non-hydratable gums.a. Water Degumming: Hydratable gums are removed by treating oils with water and separating the gums. The gums can be dried to produce lecithin.b. Acid Degumming: Non-Hydratable gums are removed by treating oils with acids and separating the gums.NeutralizingThe purpose of Neutralizing Vegetable Oils is to remove Free-Fatty Acids (FFAs). Traditionally, FFAs are treated with caustic soda (NaOH). The reaction produces Soaps which are separated from the oil. Because trace amounts of soaps remain in the oil, the oil is either washed with water or treated with Silica.Some processors prefer not to perform caustic neutralizing. Instead, they prefer Physical Refining in which the FFAs are evaporated from the oil under high temperature and vacuum. This process can be combined with deodorization step described under FFA stripping.Physical Refining process is preferred because (a) it does not produce soaps; (b) it recovers fatty acids that provide better cost recovery; (c) there is smaller yield loss compared to caustic refining—especially for oils with higher FFAs; and (d) it is a chemical-free process.BleachingThe purpose of Bleaching is to remove color pigments contained in Vegetable Oils. The oil is treated with Bleaching Clays that adsorb the color pigments. The clay is filtered and the clean bleached oil is stored for further processing. Process flow diagram is attached.DeodorizingThe purpose of Deodorizing Vegetable Oils is to remove odor substances. The oil is subjected to steam distillation under high temperature and vacuum to evaporate all odor substances. The resulting deodorized oil is almost bland and tasteless.

1) We use auto welding machine to make the reactor,which can quarrantee the quality of welding seam,avoid cracking and has a long life for about 8 years.2) Professional heating treatment and x-ray detection chamber for welding seam .3) Vacuum system to prevent oil gas be back to reactor causing accident.4) With professional thermometer , professiona pressure gauge and safety valve.

Environment friendly:

1) Dedusting system to prevent gas and dust from coal burning2) The exhaust gas will be recycled for heating reactor ,no gas pollution3) Well sealing on every junction parts to prevent gas leak,no smelly

Longer service life :Using Q345R special steel plate ,welding seam with auto welding an will get heating treatment and x-ray detection to extend the life of reactor to the most extend, and the life will 8 years.

Energy saving:1) Well sealing for heating system ,no gas leak and saving fuel.2) The exhaust gas will be recycled for reactor heating.

Transport of material in a single-screw press Cooking Oil Production Line depends mainly on friction between the material and the barrel's inner surface and the screw surface during screw rotation. Thus, Shandong Leader Machinery Co.,ltd. have a solid core component, like seed hulls, LD Edible Cooking Oil Refinery Plant sunflower oil processing machine corn oil making machine is often necessary to produce the fraction. This sometimes causes excess frictional heat, large energy consumption and oil deterioration. Furthermore, if single screw presses LD Edible Cooking Oil Refinery Plant sunflower oil processing machine corn oil making machine are not configured with breaker bars or other special equipment, Shandong Leader Machinery Co.,ltd. provide inadequate crushing and mixing.Our twin-screw oil press Cooking Oil Production Line can be expected to solve these problems because of the higher transportation force, similar to a gear pump, and better mixing and crushing at the twin-screw interface. Shandong Leader Machinery Co.,ltd. The oil expressed with twin-screw press had less foreign material than the oil from the single-screw press. Other properties of the oil were also good. Energy consumption of the twin-screw press Cooking Oil Production Line was more efficient.
